Megawatt-hour (MWh)

Equal to 1,000 kilowatt-hours or 1 million watt-hours.


Refers to wind projects where a private contractor builds a new facility without a power purchase agreement and guaranteed revenue stream. In a deregulated power market a merchant wind projects sell their electricity at spot market prices.

Meteorological Tower ("Met Tower")

A tower used at a potential project site which has equipment attached to it which is designed to assess wind resource. Generally a met tower will have anemometers, wind direction vanes, temperature and pressure sensors, and other measurement devices attached to it at various levels above the ground.

Minnesota Flip

The Minnesota Flip is a business model designed to help local wind project owners with minimal tax appetite pair up with a larger entity that has a more substantial tax burden. Because the tax credits available to project owners are proportional to their level of ownership in the project, the tax motivated entity is the majority owner in the first ten years of production and pays a “management fee” to the local owner in lieu of production payments. Once the tax incentive period ends after year 10, the majority ownership of the project “flips” to the local owner, and the tax-motivated investor takes a minority share in the project. For more information, see “The Minnesota Flip” section of the Toolbox.

Modified Accelerated Cost-Recovery System (MACRS)

Businesses can recover investments in certain property through depreciation deductions. The MACRS establishes a set of class lives for various types of property, ranging from three to 50 years, over which the property may be depreciated. For solar, wind, and geothermal property placed in service after 1986, the current MACRS property class is five years. With the passage of the Energy Policy Act of 2005, fuel cells, microturbines, and solar hybrid lighting technologies are now classified as 5-year property as well. 26 USC § 168 references 26 USC § 48(a)(3)(A) with respect to classifying property as "5-year property" and EPAct 2005 added these technologies definition of energy property in § 48 as part of the business energy tax credit expansion.

Multiplier Effect

The term “multiplier effect” as it pertains to the local economy and wind project development describes how increased spending in one part of a economy starts a chain reaction that results in an overall increase in economic activity. When a consumer spends money to buy goods or services at a local business, the local business will, in turn, spend some of this money locally on additional goods and services, and the local providers of these goods and services will likewise spend some of this money locally. In this way, money recirculates within local economies, creating wealth broadly through ongoing cycles of buying and selling. In contrast, when a consumer spends money outside of his or her local economy, it does not benefit local businesses or the employees of these businesses but instead benefits individuals outside of the community.

Municipal Utility ("Muni")

A utility owned by a city to supply utility services to residents in that city. Generally, surpluses in revenues or over-expenditures are contributed to the city budget.

Municipal Wind Power

Wind energy projects developed by small political subdivisions of cities and townships, rural electrification cooperatives, and other municipal or quasi-municipal entities or municipally owned corporations that provide electric transmission, distribution or generation services.
